Optimization of Flapper Compliant Mechanism Using Fuzzy Logic Combined Taguchi Method

Abstract:

This paper focuses on the application of fuzzy logic-based Taguchi method for multi-objective optimization in compliant flapper mechanism. The input parameters such as input torque and crank angular are optimized with considerations of the multiple performance measures as angular displacement and stress of flexible segment. The results revealed that the input torque at level 1 of 2 Nm and crank angular at level 2 of 90 degree are favorable parameters for compliant flapper mechanism. Based on anglysis of variance (ANOVA), the result shown that input torque is the most significant with percent contribution of 89%.
